b.)T-max 100 sheet film; CAUTION; this film builds up contrast very
easily but is still an excellent choice because of the long straight
line portion of the H&D curve. Development time is critical as the
highlights will tend to have too much contrast to print well.

You can also use Tri-X Pan Professional sheet film with HC-110
diluted 1:9 @ 68F for 5 minutes.

3. Exposure times can be determined by a fixed increment test strip.
For a 35mm slide to a 4x5 internegative, try as a starting point,
f/22 @ 3 second increments fior at least 8-10 increments. If
possible place the increment through a highlight and a shadow area
each time.

4. Contrast filters can be used to change the relative brightness of
subjects contained in the transparacy so that the subject with a
color similar to the filter color will appear lighter and the colors
that are blocked by the filter will appear darker in the final
print. This produces a similar effect as when the filters are used
on the camera lens when the subject was photographed. Red, orange and
yellow filters will darken blue skies, green filters will lighten
foliage, etc. If the filter was not employed when cutting the test
strip remember to use the filter factor when exposing the print.
